Description

This block converts an input signal of real double or integer data type to an integer
or real double data type. This block is particularly useful to connect a block which
accepts or produces only integer data type with another block which produces or
accepts only double data type.

It can be also use to get the least significant half of the input by a downgrade
conversion like int16 to int8. For this use case and if you do not want a type
conversion, you can also use the EXTRACTBITS block
with the Bits to extract parameter set to
Lower half.

For an upgrade conversion of a signed integer to another signed integer, the sign
bit is propagated.

When the output is an integer and when overflow occurs the block gives three different
forms of results :

A normal non saturated result. By example, if type is int8 and the result is 128,
the block output value will be -128.

A saturated result. For the previous example the block output value will be 127

An error message warning the user about the overflow.

The user can select one of these three forms by setting the
Do on Overflow
field to 0, 1 or 2.
